Bug Description

I had a 'reasonalbly' stable 5.1.31-xtradb, downloaded .deb from percona, which I could crash only with specific queries, but the latest 5.1.33 build crashes at startup after the upgrade:

Version: '5.1.33-xtradb4-log' socket: '/var/run/mysqld/mysqld.sock' port: 3306 (Ubuntu)
090410 11:06:05 - mysqld got signal 11 ;
This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
We will try our best to scrape up some info that will hopefully help diagnose
the problem, but since we have already crashed, something is definitely wrong
and this may fail.

key_buffer_size=16777216
read_buffer_size=131072
max_used_connections=5
max_threads=400
threads_connected=5
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 890846 K
bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
terribly wrong...

Trying to get some variables.

The manual page at http://dev.mysql.com/doc/mysql/en/crashing.html contains
information that should help you find out what is causing the crash.

I need symbol information of
"
/usr/sbin/mysqld [0x8034cc]
/usr/sbin/mysqld [0x807f94]
/usr/sbin/mysqld [0x808cbb]
/usr/sbin/mysqld [0x73a131]
"
If there is no symbol information, it is nearly impossible to analyze.

I don't have not stripped binary of the executable.

Can someone extract the addresses to symbols?
Or, where the not stripped binary is?
